Draw a ΔABC, where AB = 4 cm, BC = 6 cm, CA = 7 cm.

Draw the line segment PQ = 5.6 cm. 

If B is the mid-point of \(\overline{ AC } \) and C is the mid-point of \(\overline{ BD } \), where A, B, C and D lie on a straight line, say why AB = CD?

If A, B and C are three points on a line such that AB = 5 cm BC = 3 cm and AC = 8 cm, which one of them lies between the other two?
